Cutting guide
You can use a bespoke cutting guide to help you guide your fairing block through the band saw.
You can create an 'L' shaped cutting guide by joining to pieces of wood together. The pieces need
to be the same length or longer than the Fairing block.
Use the holes located in the corners of the fairing block to secure it to the cutting guide.
